The FBI and U.S. Postal Service agents are investigating bogus official-looking letters sent to voters in at least 28 Florida counties questioning their citizenship and their eligibility to vote, NBC News has learned.

David Couvertier, a spokesman for the FBI in Tampa, said his office opened up an investigation into the possible attempt at voter intimidation on Wednesday after receiving reports that eligible voters throughout the state have received the letters.

"We're taking it as a serious situation," he said. "We're looking at everything from civil rights violations to election fraud -- to everything in between."

Chris Cate, a spokesman for the Florida Secretary of State's Office, told NBC News, "We believe these letters appear to meet the standard of voter intimidation," Between 50 and 100 such letters have been reported to state officials so far, "and those are only the ones we know about. We're encouraging people to come forward."

2. The entire election process in this country needs some serious reform. n/t

3. Something fishy going on here ....... further in the story it states:

"It's not clear who sent the letters, which were machine postmarked in Seattle. Couvertier said the FBI in Tampa is working with its Seattle office to track down the perpetrator.

Cate said a "significant majority have gone to Republican voters, but not exclusively. We've got Democrats who received the letters, we've got independents. We're telling everybody to be on the lookout."
